POWERFUL Bulldogs recruit Tony Williams aims to repay the faith shown in him by coach Des Hasler at his new club this year.

The Australian international was coached by Hasler and played in Manly's 2011 grand final winning team.

He has publicly credited Hasler for his positive influence on his career.

After leaving Manly, Hasler made his way to a new kennel at Belmore last season taking the Bulldogs to a grand final, losing 14-4 to Melbourne Storm in the premiership decider.

Williams, the man nicknamed T-Rex, signed a four-year contract with the Bulldogs midway through last year. He continued to play for Manly, and by his own admission he would say his form while good at times, also had its moments of inconsistency.

The Cabramatta Junior Rugby League Club junior, grew up in Liverpool, and his first grade club was Parramatta. He debuted in first grade with the Eels on the wing in 2008, and then switched to Manly in 2009.

It was evident by his imposing physique, that he was destined for a career in the backrow.

His size and impact as a running second rower was used to the maximum by his then Manly mentor Des Hasler in 2011, when Manly won the title in 2011.

Williams stands 194 centimetres tall and weighs 124 kilograms.

On his day there is no more destructive forward in the game and when he hits in tackles it his with the force of sledgehammer.

Williams, 24, has also played twice for NSW, five Tests for Australia and 84 NRL games for Parramatta (2008), Manly (2009-2012) and the Bulldogs will be third club when season 2013 kick-off.

The Bulldogs opening game of the 2013 season is against North Queensland at ANZ Stadium, on Saturday, March 9.

No trial games have been announced by the Bulldogs at this stage.

The Bulldogs are expected to be among the top team again in 2013 with Williams' signing further strengthening its forward stocks.
